Créponné is a traditional lemon sorbet, created by Gilbert Soriano of the Crèmerie l'Oranaise in Oran. It is made by mixing lemon zest and juice with boiling sugar syrup, leaving it to rest in the freezer for a couple of hours, and then mixing it again with whipped egg whites.
The concoction is left in the freezer until the next day, although it is advisable to pull it out every half an hour for the first few hours of freezing to beat the mixture with the whisk until the sorbet sets. Créponné is a dessert usually made at home, but numerous street vendors and ice cream shops in Oran offer it during hot summer days.
